http://inventors.about.com/od/bstartinventions/a/Bar-Codes.htm First "Modern looking" UPC system was installed for use at a Marsh grocery in 1973 ~ you are off about a decade.
UPC bar codes of that type did not come into popular usage until the late 80s and early 90s, in supermarkets first, but certainly not ever on a college ID in 1981. They simply did not exist in such a form at that time because
there were no commercially-available devices to read them (outside of a laboratory).
I went to a similarly-appointed college (graduated in '80) and I still have my ID (a small laminated Polaroid card). The Columbia ID in the photo is far too graphically modern to have been produced anywhere near the same time period.
